Instructions on how to carry out a Restore to Factory setting are in the link after the Caution.
When you have restored to factory settings you should set up an internet connection, install anti-virus software, update all drivers from the Dell web site and install all Windows Updates. Run Disk CleanUp and defragment at intervals.
You should then be in a position to reinstall programmes. With that in mind make a list of programmes to be installed and check that you have the means to do it. Check that you have the necessary information to recreate your internet connection on the new
system. Make a list of what you need to do and the order in which you intend to do each task. This will help you considerably when you carry out the operation. If you have a second computer available when you rebuild your computer system, this can help if
you hit a problem and need to check online.
